Each application, publication, and patent listed in this paragraph are hereby incorporated by reference in their entireties.
TECHNICAL FIELD
The present disclosure relates to the technical field of heat exchange, and in particular to a heat exchange assembly and a heat exchange device.
BACKGROUND
For an arrangement of a distance between a heat exchanger and a fan in the prior art, an influence of a resistance caused by the distance is usually not considered. Since the increase of the air intake resistance caused by an improperly arranged distance will adversely affect the aerodynamic efficiency, air volume and noise and the like of the whole machine, it is necessary to optimize the arrangement of the distance.
Thus, the increase of the air intake resistance caused by the improperly arranged distance between the heat exchanger and the fan in the prior art, causes the problems of the drop of the aerodynamic efficiency and the rise of the noise of the whole machine.
SUMMARY
An objective of the present disclosure is to provide a heat exchange assembly and a heat exchange device, to solve the problem of the increase of the air intake resistance caused by the improperly arranged distance between the heat exchanger and the fan in the prior art.
In order to achieve the objective above, according to one aspect of the present disclosure, a heat exchange assembly is provided. The heat exchange assembly includes: a heat exchanger; a fan, where the heat exchanger and the fan are spaced apart, and the heat exchanger is located in an air intake direction or in an air outgoing direction of the fan; the fan has an air opening; the air opening faces the heat exchanger; and a shortest distance H between the air opening of the fan and the heat exchanger, and a diameter D of an impeller of the fan satisfy
2 ⁢ H D > 1.05 .
Further, a projection of the air opening of the fan projected on the heat exchanger is located within an edge of the heat exchanger.
Further, a projection area S0 of the heat exchanger projected on a reference plane parallel to the air opening is greater than a projection area SP of the air opening of the fan projected on the reference plane.
Further, an air outgoing area S1 of the heat exchanger is greater than an air intake area S2 of the air opening of the fan.
Further, the air outgoing area S1 and the air intake area S2 of the air opening of the fan satisfy
1 < S ⁢ ⁢ 1 S ⁢ ⁢ 2 < 3 . 5 .
Further, the heat exchanger is a curved plate-shaped structure, or a bent plate-shaped structure formed by attaching a plurality of plate-shaped sections sequentially.
Further, the heat exchanger is the bent plate-shaped structure formed by attaching the plurality of plate-shaped sections sequentially, and a plate section facing the air opening is arranged to be inclined to the air opening.
Further, the heat exchanger surrounds to form a heat exchanging region, and the air opening of the fan is located in the heat exchanging region.
Further, the heat exchanger is a plate-shaped structure, and the heat exchanger is parallel to the air opening, or the heat exchanger is arranged to be inclined to the air opening.
Further, the heat exchanger is one of a V-shaped heat exchanger, a W-shaped heat exchanger and a wave-shaped heat exchanger.
According to another aspect of the present disclosure, a heat exchange device is provided. The heat exchange device includes the heat exchange assembly above.
Further, the heat exchange device is an air conditioner.
According to the technical solutions of the present disclosure, the heat exchange assembly includes the heat exchanger and the fan. The heat exchanger and the fan are spaced apart, and the heat exchanger is located in an air intake direction or in an air outgoing direction of the fan. The fan has the air opening and the air opening faces the heat exchanger. The shortest distance H between the air opening of the fan and the heat exchanger and the diameter D of the impeller of the fan should satisfy
2 ⁢ H D > 1.05 .
When the heat exchange assembly operates, the fan starts. Under the action of the negative pressure, the air is blown from the fan to the heat exchanger, or the air exchanges heat through the heat exchanger first, and after the heat is exchanged, the air flows through the air opening of the fan and is blown out of the fan. The air intake resistance presents a variation trend that the air intake resistance decreases sharply first and then gradually tends to be stable along with the increase of the distance between the heat exchanger and the fan, therefore, when the diameter D of the impeller and the shortest distance H between the heat exchanger and the air opening of the fan satisfy
2 ⁢ H D > 1.05 ,
it can be ensured mat the air intake resistance is smaller and tends to be stable, thereby preventing effectively the drop of the aerodynamic efficiency and the rise of the noise of the whole machine due to the increase of the air intake resistance.

As shown in FIGS. 1 to 8, the heat exchange assembly includes a heat exchanger 10 and a fan 20. The heat exchanger 10 and the fan 20 are spaced apart, and the heat exchanger 10 is located in an air intake direction or in an air outgoing direction of the fan 20. The fan 20 is provided with an air opening 21, and the air opening 21 faces the heat exchanger 10. The shortest distance H between the air opening 21 of the fan 20 and the heat exchanger 10, and a diameter D of an impeller of the fan 20 satisfy
2 ⁢ H D > 1.05 .
Specifically, when the heat exchange assembly operates, the fan 20 starts. Under the action of a negative pressure, the air is blown from the fan 20 to the heat exchanger 10; or the air exchanges heat through the heat exchanger 10 first, and after the heat is exchanged, the air flows through the air opening 21 of the fan 20 and is blown out of the fan 20. The air intake resistance ΔP (Pa) presents a variation trend that the air intake resistance ΔP decreases sharply first and then gradually tends to be stable along with the increase of the distance between the heat exchanger 10 and the fan 20, therefore, when the diameter D of the impeller and the shortest distance H between the heat exchanger 10 and the air opening 21 of the fan 20 satisfy
2 ⁢ H D > 1.05 ,
it can be ensured that the air intake resistance is smaller and tends to be stable, thereby preventing effectively the drop of the aerodynamic efficiency and the rise of the noise of the whole machine due to the increase of the air intake resistance.
It should be noted that when an air intake opening of the fan faces the heat exchanger 10, where the air opening 21 is the air intake opening, the air flows through the heat exchanger 10 first, and then flows into the fan 20. When an air outgoing opening of the fan 20 faces the heat exchanger 10, where the air opening 21 is the air outgoing opening, the air flows through the fan 20 first and then is blown to the heat exchanger 10.
The following description will be made by taking the air opening 21 as the air intake opening as an example.
In order to ensure the heat exchange effect of the heat exchange assembly and the starting efficiency of the whole machine, in the present disclosure, the projection of the air opening 21 of the fan 20 projected on the heat exchanger 10 is located within an edge of the heat exchanger 10. In such a way it can be ensured that, before entering the fan 20 through the air opening 21, all air exchanges heat through the heat exchanger 10, thereby ensuring the heat exchange efficiency of the heat exchange assembly.
Optionally, the fan 20 is a cross-flow fan or a centrifugal fan.
The following description will be illustrated via five embodiments according to different specific structures of the heat exchanger 10.
First Embodiment
As shown in FIGS. 1 to 5, in this embodiment, the heat exchanger 10 is a bent plate-shaped structure formed by attaching a plurality of plate-shaped sections sequentially, and an air outgoing area S1 of the heat exchanger 10 is greater than an air intake area S2 of the air opening 21 of the fan 20.
It should be noted that the air outgoing area S1 of the heat exchanger 10 refers to the whole area of the air blow after the air flows through the heat exchanger 10. In FIG. 2, S1 refers to the whole surface area of a side of the heat exchanger 10, and the air flows out of the side of the heat exchanger.
Specifically, the heat exchanger 10 is formed by attaching three plate-shaped sections sequentially to be a U-shaped heat exchanger. Moreover, the plate section located in the middle is arranged to face the air opening 21 of the fan 20 directly. Of course, in other embodiments, for example, in the fifth embodiment, the middle plate section can be arranged to be inclined to the air opening 21.
Optionally, the air outgoing area S1 of the heat exchanger 10 and the air intake area S2 of the air opening 21 of the fan 20 satisfy
1 < S ⁢ ⁢ 1 S ⁢ ⁢ 2 < 3 . 5 .
It should be noted that the ratio of S1/S2 should be controlled appropriately to prevent the ratio of S1/S2 from being excessive small or excessive large. When the ratio of S1/S2 is excessive small, the size of the heat exchanger 10 cannot meet the requirements for the heat exchange. When the ratio of S1/S2 is excessive large, a larger air intake resistance ΔP will be produced.
As shown in FIG. 1, a projection area S0 of the heat exchanger 10 projected on a reference plane 30 parallel to the air opening 21 is greater than a projection area SP of the air opening 21 of the fan 20 projected on the reference plane 30. Through the above arrangement, the area of the heat exchanger 10 can be large enough to ensure that, before entering the fan 20 through the air opening 21, the air all exchanges heat through the heat exchanger 10, thereby ensuring the heat exchange efficiency of the heat exchange assembly.
Specifically, in FIGS. 1 to 4, a portion of the heat exchanger 10 faces the air opening 21 and is parallel to the air opening 21, therefore the portion, the reference plane 30, and the plane in which the air opening 21 is disposed, are parallel to each other. In this way, the projection area described above is the structural area corresponding to the structure.
As shown in FIGS. 1 to 3, the heat exchanger 10 surrounds to form a heat exchanging region 11, and the air opening 21 of the fan 20 is located in the heat exchanging region 11. Since the air opening 21 is located in the heat exchanging region 11, after exchanging heat through the heat exchanger 10, the air can enter the fan 20 smoothly, thereby ensuring the heat exchange efficiency of the heat exchange assembly.
As shown in FIG. 5, in this embodiment, while the ratio of the shortest distance H between the heat exchanger 10 and the air opening 21 of the fan 20 to the diameter D of the impeller of the fan 20 varies, the air intake resistance ΔP varies as well. The specific variation relationship is that: the air intake resistance ΔP (Pa) presents a variation trend that the air intake resistance ΔP decreases sharply first and then gradually tends to be stable along with the increase of the distance between the heat exchanger 10 and the fan 20.
Thus, apart from the ratio of S1/S2, the ratio of the shortest distance H between the heat exchanger 10 and the air opening 21 of the fan 20 to the diameter D of the impeller of the fan 20 has a larger influence on the air intake resistance ΔP.
Second Embodiment
Distinguished from the first embodiment, the heat exchanger 10 has a different structure.
In this embodiment, as shown in FIG. 6, the heat exchanger 10 is a curved plate-shaped structure.
Likewise, the heat exchanger 10 can surround to form the heat exchanging region 11. The air opening 21 of the fan 20 is located in the heat exchanging region 11. Of course, the air opening 21 may also not be located in the heat exchanging region 11.
Compared with the embodiment of FIG. 1, the projection area S0 of the heat exchanger 10 projected on the reference plane 30 is not changed, and the projection area SP of the air opening 21 of the fan 20 projected on the reference plane 30 is also consistent with that shown in FIG. 1.
Compared with the heat exchanger 10 in the first embodiment, the heat exchange area of the heat exchanger 10 in this embodiment is larger, and the heat exchange effect per area unit is better.
Third Embodiment
Distinguished from the first embodiment, the heat exchanger 10 has a different structure.
In this embodiment, as shown in FIG. 7, the heat exchanger 10 is a plate-shaped structure, and the heat exchanger 10 is configured to be parallel to the air opening 21.
In this embodiment, the heat exchanger 10 cannot surround to form the heat exchanging region 11, and is merely arranged at the air intake side of the fan 20.
Thus, in this embodiment, the air intake area of the heat exchanger 10 is equal to the air outgoing area. In order to ensure the consistence with other embodiments, in FIG. 7, S1 is still used to represent the air outgoing area of the heat exchanger 10.
Compared with the embodiment of FIG. 1, the projection area S0 of the heat exchanger 10 projected on the reference plane 30 is not changed, and the projection area SP of the air opening 21 of the fan 20 projected on the reference plane 30 is also consistent with that shown in FIG. 1.
Compared with the heat exchanger 10 in the first embodiment, the heat exchanger 10 in this embodiment has a more simple structure.
Fourth Embodiment
Distinguished from the third embodiment, the heat exchanger 10 has a different structure.
In this embodiment, as shown in FIG. 8, the heat exchanger 10 is a plate-shaped structure, and the heat exchanger 10 is configured to be inclined to the air opening 21.
In this embodiment, the heat exchanger 10 cannot surround to form the heat exchanging region 11, and is merely arranged at the air intake side of the fan 20.
Thus, in this embodiment, the air intake area of the heat exchanger 10 is equal to the air outgoing area of the heat exchanger 10. In order to ensure the consistence with the other embodiments, in FIG. 8, S1 is still used to represent the air outgoing area of the heat exchanger 10.
Compared with the embodiment in FIG. 1, the projection area S0 of the heat exchanger 10 projected on the reference plane 30 is less than the air intake area of the heat exchanger 10 itself. Moreover, the projection area SP of the air opening 21 of the fan 20 projected on the reference plane 30 is consistent with that shown in FIG. 1.
Compared with the heat exchanger 10 in the first embodiment, the heat exchanger 10 in this embodiment has a more simple structure.
Fifth Embodiment
Distinguished from the first embodiment, the plate-shaped section facing the air opening 21 is configured to be inclined to the air opening 21. The specific configuration can be referred to the description for FIG. 8.
Compared with the heat exchanger 10 in the first embodiment, the heat exchange area of the heat exchanger 10 in this embodiment is larger, and the heat exchange effect per area unit is better.
Of course, besides the heat exchangers 10 shown in the figures, heat exchangers of various shapes, such as a V-shaped heat exchanger, a W-shaped heat exchanger, a wave-shaped heat exchanger and the like, are likewise applicable for the above-mentioned arrangement.
